The Lowdown
Rightio, let’s have a look at what’s brewing for Karramarro over the next couple of weeks. It’s a point break so it handles swell well, and it’s set up for a north-west swell. The water’s sitting at 74°, which is much warmer than normal for this time of year – a solid 4° above average, so it’s gonna feel like a warm bath out there.
First up, we’ve got a bit of a flat spell to kick things off. Nothing really worth paddling out for on Tuesday 1st September – just a messy 5ft cross-on breeze and weak energy (341). Wednesday and Thursday are even smaller, with glassy mornings but barely a ripple. Friday and Saturday mornings are flat and clean, but not enough push to get excited about. The first real sign of life shows up on Saturday afternoon, 5th September: a 4ft north-west swell, period up to 11 seconds, and the energy’s climbing to 279. Still a bit onshore, so it’s a maybe.
Sunday morning, 6th September, is where it starts to get interesting. We’ve got 4ft of north-west groundswell, period 12 seconds, and glassy conditions. The energy’s jumped to 453 – that’s moderate wave energy. This is a proper long-period groundswell, so it’ll wrap nicely around the point. The sets will be clean and well-shaped, with longer gaps between them, making paddling out a bit easier. This is a standout window for the advanced crew.
Monday 7th September drops back a bit – smaller and cross-on again. But Tuesday morning, 8th September, brings another clean window: 4ft west-north-west, glassy, and energy at 286. Not a monster, but clean and ridable.
The biggest pulse of the whole run looks like Wednesday 9th September. That morning we’ve got 5ft from the north-west, period 11 seconds, and the energy’s hitting 774 – that’s strong. Winds are light cross-shore, not perfect, but the size and power are there. This is getting into the territory where it’s only for experienced surfers. The afternoon stays solid at 6ft, but the cross-on breeze picks up a bit. Still, if you’re after size, this is the day.
The following week is a mixed bag. Thursday 10th September hangs around 4ft to 5ft, but winds are cross-on, so not ideal. Friday 11th September is small and wet. Saturday 12th and Sunday 13th September serve up surfable 4ft to 5ft waves with glassy conditions – the swell period drops to 7-8 seconds though, so it’s shorter period, less grunt. These are low-energy days but still fun for a grovel.
Monday 14th September is a write-off. Tuesday 15th September, though, brings a return to clean conditions: 5ft north-west, glassy, and energy at 281 in the morning, climbing to 365 by afternoon. That’s a solid day, with clean lines and good shape. Then Wednesday 16th September morning holds 4ft north-west, period 10 seconds, with clean offshore winds – that’s another good session for the last day of the forecast.
Overall, the standout is Sunday 6th September with that long-period groundswell and glass. The second best is Tuesday 15th September for the clean afternoon session. The mid-week pulse on 9th September is the biggest, but the wind is a bit scratchy. Crowds are likely at Karramarro, so if you’re heading out on the good days, expect company.

Information about the Karramarro Surf forecast
The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Karramarro is 3 km (2 miles) from Zarautz. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in Zarautz. Zarautz has rooms for a wide range of budgets as well as car hire and transport links.
